SPECIFICATION forming part of Letters Patent N 0. 623,455, dated April 18, 1899.

Application filed November 80, 1898. Serial No. 697,865. (No model.)

To all whom it may concern;

Be it known that I, CHANDLER l. Yoncn,

a citizen of the United States, residing at Montague, in the county of Marion and State of Florida, have invented new and usefulImprovements in Hammers, of which the following is a specification.

My invention relates to an improvement in hammers.

The object of my invention is to provide an attachment pivotally secured in a recess in the head of the ham mer, which maybe thrown into position to afford an increased leverage in drawing nails.

Other objects of the invention relate to certain details of construction insuring facility in use, reliability in operation, and stability in structure, all of which will be clearly understood from the detailed description herein, taken in connection with the accompanying drawings, illustrating the invention, in which Figure 1 represents a perspective view of the head of a hammer provided with my improvement, the latter beingin its inoperative position; and Fig. 2 is a sectional view of the same, the attachment being shown in full lines in operative and in dotted lines in inoperative position.

The numeral 1 indicates the head of the hammer, secured on the handle 2 and preferably having the integral depending tongues for bracing the handle. The head 1 is provided in its central upper portion with a recess a, in which is pivotally secured my im- 4 proved attachment 5,which I will term a fulcrum-block. The pivot 6 of this part is located in the upper part and near the side of the recess nearest the claws, as shown. In

in the head of the hammer, as by a rivet 9. That portion of the block extending into the recess at to receive the pivot 6 presents two opposite flat sides, as shown, against either of which the spring 8 is adapted to bear according as the block 5 is turned into or out of operative position and to hold said block securely in'either of said positions. The outer sides of the fulcrum-block presents a curved surface 10, upon which the hammer rocks in the operation of drawing a nail. In said curved surface is provided a notch 11 for convenience in raising the fulcrum-block out of the recess 4 to turn the former into position for use.

The ad vantage of my improvement will be readily understood. \Vhen the device is in the operative position shown in full lines in Fig. 2, it will aitord great leverage in the operation of withdrawing a nail, as will be understood. \Vhen not in use, it is turned back into the recess 4, and is held therein by the spring 8 and presents no obstacle to the use of the hammer for ordinary purposes.

Having thus fully described my invention, what I claim as new is 1. A hammer having a recess in its head and a fulcrum-block pivotally secured in said recess and normally inclosed therein and designed to be turned into position to operate as a fulcrum for the hammer, substantially as described. I

2. A hammer having a recess in its head, a fulcrum-block pivotally secured in said recess and normally inclosed therein and designed to be turned into position to operate as a fulcrum for the hammer, and means for holding said fulcrum-block in either of said positions, substantially as described.

A hammer having a recess in its head, a fulcrum-block pivotally secured in said recess and normally inclosed therein and designed to be turned into position to operate as a fulcrum for the hammer, and a spring secured in the head and bearing on said fulcrum-block whereby to hold the same in either of said positions, substantially as described.

4. A hammer having a recess in its head, a fulcrum-block pivotally secured at one end in said recess and normally inclosed therein I In testimony whereof I have hereunto set and designed to be turned int-o position to 0pmy hand in presence of two subscribing Witerate as a fulcrum for the hammer, and a nesses.
